Yep, a dosbox.conf file is supported and automatic executed at start..
There is a command in dosbox to create a default dosbox.conf
config -writeconf [path to dosbox\]dosbox.conf
Of course this drive (path to dosbox) has to be mounted.
After this its easy to edit and modify it, there is some explanation inside..
The most important is the autoexec part, there you can mount all the needed drives and CDrom(s).. just the way ' normal' DOS see it, so there is no need to reinstalll / reconfigure games 
There is one important thing I noticed.. mounting a drive like it say in the windoze FAQ like this ;
mount c "c:\"
Does work... but its impossible to go into subdirs...
Mounting like this ;
mount c: c:
mount c c:
mount c "c:/"
Alll do work..
So.. actually the slash is unix like..Finally.. this is how my dosbox.conf looks like.. ;

# fullscreen -- Start dosbox directly in fullscreen.
# fulldouble -- Use double buffering in fullscreen.
# fullfixed -- Don't resize the screen when in fullscreen.

# hwscale -- Extra scaling of window if the output device supports hardware scaling.
# autolock -- Mouse will automatically lock, if you click on the screen.
# sensitiviy -- Mouse sensitivity.
# waitonerror -- Wait before closing the console if dosbox has an error.
# priority -- Priority levels for dosbox: lower,normal,higher,highest.
# Second entry behind the comma is for when dosbox is not focused/minimized.
# mapperfile -- File used to load/save the key/event mappings from.
